What

Pockethotline is a rails app that allows you to setup a "distributed hotline". This allows you to have a hotline number that is published and operators signup with their personal numbers. When someone calls the main number the operators will be called (depending on their on-call status) and connected to the main caller.

It was originally conceived as a business by Scott Magee and Chap Ambrose at the Austin Center for Design in the winter of 2011.

The software was open-sourced January 2014.

How much does it cost to run a hotline?

Hosting Costs

The minimum hosting costs are about $35 a month. This is because a background worker dyno is required. (Assuming you're using Heroku for hosting).

Phone Costs

Twilio phone numbers cost $1/month for local numbers and $2/month for toll-free.

Twilio charges you by minutes used, $0.03/minute for local and $0.05/minute for toll-free.

Twilio's published rates are $0.01 / $0.03 but that is only for the incoming call, you also have to add another $0.02 to each call because of the outgoing connection to the operators.

Basic Setup

##1. Setup accounts on:

##2. Get a phone number on Twilio Start with the free trial number or purchase another toll-free or local number.

##3. Take note of your phone number and API credentials AccountSID and AuthToken Find them under "Account Settings"

##4. Clone the repository

##10. Create database tables
$ heroku run rake db:schema:load

##11. Scale up worker dyno (required for background tasks)

##13. Add SESSION_SECRET ENV variables to heroku config First run
$ heroku run rake secret

Copy the output and use it here:
$ heroku config:set SESSION_SECRET=XXXXXXXXXXXXXX

##14. Setup the on-call scheduler

  1. $ heroku addons:add scheduler
  2. $ heroku addons:open scheduler
  3. Click "Add Job"
  4. In the left-most field enter "rake oncall_scheduler"
  5. Change frequency to "Hourly"
  6. Set next run to "XX:00" (The XX will depend on the current time.)
  7. Click "Save"

##15. Create yourself an account (edit these values)

  $ heroku run rails console
  $ u = User.new(
    :name => 'my name', 
    :email => '[email protected]', 
    :phone => '215-359-5228', 
    :password => 'setyourpasswordhere'
    )
    u.admin = true
    u.on_call = true
    u.save!

##16. Login to your account $ heroku open

##17. Update Twilio with your app's domain

  • Click on 'Numbers' in the nav bar
  • Click on your phone number
  • Change the 'Voice Request URL' to https://myhotline-name.herokuapp.com/twilio/start
  • Set request method to [POST]

##18. Call the hotline and see if it's working!

  • Don't call from the same number that you added for yourself
  • If you're using your free demo Twilio account you'll hear a pre-roll message. That will go away when you upgrade your account.
  • Your call should be connected after the greeting message is used.
  • If calling via Gtalk fails to connect, try a real land or cell line.

##19. Yeah!

#Advanced Setup of Hotline Supporters

##1. Create an account on Stripe.com

##2. Set Stripe publishable key in config Uncomment (remove leading '#') and edit values in config/hotline.rb

  • config.x.stripe.secret_key

  • config.x.stripe.publishable_key

  • config.x.stripe.publishable_key

##3. Add Stripe API key $ heroku config:set STRIPE_SECRET_KEY=XXXXXXXXXXXXXX

##4. Save changes and deploy $ git commit config/initializers/hotline.rb -m "add stripe details" $ git push heroku

##5. Visit suporters page

https://.../supporters/new

Stripe requires SSL to be enabled, if you're using your default heroku domain you will seemlessly piggy-back on the wildcard certificate at *.herokuapp.com.

If you want to use a different domain you may have to purchase and setup your own certificate.

#Forward unanswered calls, change recordings, Twitter integration, etc
